WRITING-DESK AND TABLE cz'olvilsml-zo.v

SPECIFICATION forming part of Letters Patent No. 364,684-, dated June14, 1887. Application filed March 14,1887. Serial No. 230,779. (Nomodehl To @ZZ whom t may concern.'

Be it known that I, CHARLEs SONNE, a citizen of the United States ofAmerica, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in aWritingDesk and Table Combined, ofwhich the following is aspecification, reference being had therein to the accompanying drawings.

1o This invention has for its object to provide atable that by a simplemanipulation can be converted into a writing-desk; and for thatv purposeit consists of the novel devices and combinations of devices,hereinafter described i5 and specifically claimed.

In the accompanying drawings, Figure l represents a sectional endelevation of the table on line l l in Fig. 2; Fig. 2, a plan of of thesame, vboth table-top leaves being swung 2o `to a vertical position;Fig. 3, a transverse vertical section, on line 3 3 in Fig. 2, of thetable as converted into a desk; and Fig. 4 a longitudinal verticalsection of same on line 4 4in Fig. 1. y

Corresponding letters in the several iigures of the drawings designatelike parts.

/f A denotes, the table-frame, supported on legs a and provided in aboutits center with ,i longitudinal partition B, re-enforced on top 3; by `astrip, b, to which, by hinges c, is pivotally ,i secured `the forwardleaf, C, of the table-top.

The rear leaf, D, is pivotally connected again manner that the leaf Dcan be folded upon the 3 5 front leaf, C, and that both leaves thusfolded can be raised to a vertical position.

The forward portion of frame A is made to form an inclined support fortop leaf, C, as most desirable for a writing-desk, and is pro- 4o videdwith folding strips that, when interposed, will raise such top leaf to ahorizontal position, as will be desirable for a table.

This construction consists of wedge-shaped strips e, secured against theinclined upper edges of the sides of frame A by hinges f, so as to foldagainst the inside thereof, of a front strip, g, secured by hinges hagainst the upper rear edge of the front of frame A, and of cor`ner-pieces, secured to the ends of front strip,

5o g, by hinges j, in a manner that, while the top leaf, C, is lifted toclear frame A, the pieces e' tothe rear edge of leaf C by hinges d, ina\ are first folded down. Next, the corner pieces t' are swung outwardagainst the front face of strip g, to occupy a position as shown indotted lines by t in Fig. 2, and then such strip g is folded inwardagainst the rear face of the front board of frame A, when thecorner-pieces i will occupy the position shown by dotted lilies andindicated 'by i2 in Fig. 2, and then by lowering leaf C again upon suchframe it 6o will be supported thereon to bc on an inclined position; butwhile the strips e and g and the corner-piecesz' are turned to theirupright positions they will form a smooth upward continuation'of frame Aand will provide hori- 6 zontal supporting-edges for the table-leaf C.

The space in frame A back of partition B is occupied by averticallysliding shelf, K, arranged to hold books,linkstand, and pens,and with drawers for holding papers. Against 7c -the inward face of eachside board of frame A,

behind partition B, is secured a stud, m, upon which is pivoted asheave, n, and a gear-wheel, o, integral therewith, and against each endof shelf K is secured a vertical rack-bar, p, the 7 5 teeth of whichengage with the teeth of gearwheelso in a manner that a rotating move--ment of wheels a and o will transmit a verticaLZ/,tA

straight-line movement of shelf K/Obe end of a string,r, is rigidlysecured in the circumferential groove of each sheave, n. Thence thestring is wound once around such sheave n and is secured with itsopposite end against the under side of leaf D at about one-third of itsent-ire width from hinges d, in a manner that the swinging of theone-half of a revolution of leaf D from the position of forming the reartable-top to the folded position for forming the desktop willV rotatewheels n and o suffrciently for raising the shelf K from the posi- 9otion ,occupied below the table-top to the elevated position shown inFigs. 3 and 4. Vith converting the desk into a table again the shelfwill move down by its own gravity, releasing its supports by turningleaf D to cover 9 5 the rear of the table again, and when in thatposition the shelf K will be concealed.

By the abovedescribed arrangement, as will be readily seen, a piece offurniture is produced that will not vary in its appearance roo from acommon table, and which by simple movements can be instantly convertedinto a the frame A, provided with the folding strips convenientwriting-desk provided with the usual, commodities.

What I Claim is- 1. The eolnbination of the donble-leafed top D, hingedtogether` and to the frame of the table, the stud or studs m, sheave orsheaves n, cord or eords r, connecting the lid or top with said sheaveor sheaves, and the gear or gears o on the studs m, with the verticallyadjustable or movable shelf K and the rack bar or bars p, connectedthereto and engaging with the gear or gears, as set forth.

2. A combined desk and table, consisting of e and g and foldingcorner-pieces i, and the partition B, the donbleleafed lid or top D,

the two parts whereof are hinged together and to the partition B, thestuds m, sheaves n, and

gears o, and the cords yr, connecting the top or lid with the sheaves n,the movable shelf or part K, having the racks p p, engaged with thegears o, all combined and arranged substantially as set forth.

3. The combination, with table-frame A, supported on legs (t andprovided with partition B, and with sheaves n and gearwlieels o, ofshell" K, having rack-bars p, engaging with wheel o, and foldingtable-top D, coupled with sheaves a by strings r, all substantially asdescribed, to operate as specified.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES SONNE.
